PM340 Power Modules communicate with the CU305 Control Unit via the PM-IF interface.

Note:

Operation of SINAMICS S110 in conjunction with PM240?2 Power Modules is possible with firmware version V4.4 SP3 and higher.

Connection example: PM340 Power Module

Many system components are designed as base components for PM340 Power Modules. I.e. the component is mounted on the baseplate and the PM340 Power Module in front of them in a space-saving construction. Up to two base components can be mounted in front of one another.

? = Suitable as base type

O = Not suitable as base type

– = Not available (use a PM340 Power Module with integrated line filter)

Basic layout of a PM340 Power Module with line reactor as base component

The line side reactors are equipped with terminals on the line side and with a pre-assembled cable on the PM340 Power Module side. When installed, the mains terminals are at the top on frame sizes FSA to FSC, and at the bottom on frame sizes FSD and FSE.

If a line filter is installed in addition to the line reactor on frame size FSA, the components must be arranged as shown in the diagram above. In this case, the line supply connection is at the bottom.

PM340 Power Modules of frame size FSB and higher are available with integrated line filters, alleviating the need for an external line filter.

For configurations involving more than two base-type system components, e.g. line reactor + motor reactor + braking resistor, individual components must be mounted to the side of the PM340 Power Module. In this instance, the line and motor reactors must be installed behind the PM340 Power Module and the braking resistor to the side.
